I think one way in which all 3 endings are related is that they all involve some sort of death. Sara's is the death of her dreams (Harry being successful and her appearing on the game show), Randy's is his literal death in the form of a sacrifice, and Nina's is either her literal death or the metaphorical death of a part of her that allows a new part to emerge, depending on how you interpret the movie.

You don't feel you're shoehorning Sara in here? Especially since I think you're misinterpreting it -- we don't see her dream die, we see that she still has it despite everything, which is even more depressing. But even if you're not misinterpreting it, it still seems obvious to me you had to engage in some sophistry to make three of a kind here

I don't think it's shoehorning, as I'm not saying Aronofsky is using the endings to say the exact same thing, just something similar. In an earlier post I agreed with darthyoshi when he said Sara's ending doesn't completely fit. If we're looking at theme, then they're very different. I just think there are some similarities.

As for the misinterpretation, I think Sara chooses to stay with the dream instead of facing reality. Her last expression of the film is one of utter horror and panic before she suppresses it and goes back to happily embracing Harry. At that point she knows the dream is dead. It's been a false reality for a while, but the film shows us she's aware of it and chooses to live in that false world instead of deal with reality. To me, that's no longer a dream.
